为你我放弃所有却换什么
[wéi nĭ wŏ fàng qì suŏ yŏu què huàn shén me]
'For You I Give Up Everything, But for What?' implies deep dedication mixed with bewilderment. After sacrificing personal possessions or rights for another person (or thing), they find no clear result or reward for all that sacrifice. It shows regret, frustration but possibly anticipation at the same time for an understanding response from what was sacrificed to.
